We can post most anything, but the facts will remain the facts, long after the experts have had their say. Those on the ground will have to do what works, will learn as the Africans have what does not work, and the lessons will be paid for in lives.
Viral load is highest right around the time of death, but mobility isn't much. There is a trade off, a balance point between viral load and ability to function which is likely the most dangerous, but having someone who feels well enough to go out and expose others, even with a lower viral load has more potential, imho, to spread the disease. With such a low ID50, the amount probably doesn't make much difference as long as they are shedding the virus. Remember, in this case, the virus is in all the bodily fluids, not just blood. Sweat, spit, tears, semen, vaginal secretions, as well as feces, vomit, and blood count, and contaminated surfaces have the ability to harbor the virus long enough for someone else to pick it up--especially in an urban environment.
Regarding the Dallas case, I don’t think he was shedding on the first visit, or at least it would have been difficult to do so. But on the second, he definitely was.
He had diarrhea and was showing the other symptoms and that is why he was admitted then..
So that is when he was dangerous...IMO
As to the other things, like urine, sweat, etc....
You still have to have blood in these secretions..and you will find it there in the end stages...
He was entering that stage when he presented on the second visit.
The stuff works fast once the viral load overwhelms the immune system.
Sure, it can live a while on surfaces..but the time seems to be a variant based on the what the substance it, temperature, humidity, and the presence or lack of anti-microbial chemicals.
These chemicals or agents are easy to apply.
They don’t do any of these precautions in Africa. or did not initially and these easy precautions are not being used by the locals.(they may not have access to things like bleach, for example) The reusing of gloves and garb, the collective sleeping arrangements, the ignorance and outrageous beliefs or the locals is all factoring into the loss of control of the outbreak.
I believe this is why the troops are needed there to protect and control ingress, egress and flow of people near our Army medical facilities, both existing and planned..That is why the engineers are there...(I was one)
Yet each and every bit of news along these lines, results in a chorus of protest. Most of which is totally unnecessary and hyperbolic..
I am pretty much just observing it now. Like I would some sort of social experiment. It does not seem to be going well, based on the stock market reactions today.
